Switchable and Simultaneous Spatiotemporal Analog Computing with Computational Graphene-based Multilayers

Romain Christophe Rémy Fleury, Ali Momeni

In the past few years, analog computing has experienced rapid development but mostly for a single function. Motivated by parallel space-time computing and miniaturization, we show that reconfigurable graphene-based multilayerss offer a promising path towar ...

Self-consistent Hubbard parameters from density-functional perturbation theory in the ultrasoft and projector-augmented wave formulations

Nicola Marzari, Iurii Timrov, Matteo Cococcioni

The self-consistent evaluation of Hubbard parameters using linear-response theory is crucial for quantitatively predictive calculations based on Hubbard-corrected density-functional theory. Here, we extend a recently introduced approach based on density-fu ...

Parallel Implementation Technique of Digital Equalizer for Ultra-High-Speed Wireline Receiver

Yusuf Leblebici, Alessandro Cevrero, Thomas Toifl, Lukas Kull, Ilter Ozkaya, Gain Kim, Cosimo Aprile

This paper presents a parallel implementation technique of digital equalizer for high-speed wireline serial link receiver (RX). In wireline RX, inter-symbol interference (ISI) is mitigated by continuous-time linear equalizer, and the remaining ISI is cance ...

Laser-Induced Transition between Nonlinear and Linear Resonant Behaviors of a Micromechanical Oscillator

Yves Bellouard, Tao Yang

We investigate both theoretically and experimentally a laser-based controlled tuning of the nonlinear behaviors of a single mechanical resonator. Thanks to localized three-dimensional modifications induced by femtosecond-laser irradiation, a Duffing-like o ...

Saturation of the response to stochastic forcing in two-dimensional backward-facing step flow: A self-consistent approximation

François Gallaire, Vladislav Mantic Lugo

Selective noise amplifiers are characterized by large linear amplification to external perturbations in a particular frequency range despite their global linear stability. Applying a stochastic forcing with increasing amplitude, the response undergoes a st ...

Architectural Modeling of a Multi-Tone/Single-Sideband Serial Link Transceiver for Lossy Wireline Data Links

Yusuf Leblebici, Gain Kim

This paper presents a serial link transceiver (TRX) architecture that enables high-speed data transmission over a lossy backplane channel without the presence of equalization circuits. The proposed architecture employs multi-tone signaling to reduce inter- ...

Model predictive control of linear periodic systems - a unified framework including control of multirate and multiplexed systems

Colin Neil Jones

State-feedback model predictive control (MPC) of discrete-time linear periodic systems with possibly time-dependent state and control input dimension is considered. States and inputs are subject to hard, mixed, polytopic constraints. It is described how di ...

The dynamical response properties of neocortical neurons to temporally modulated noisy inputs in vitro

Michele Giugliano

Cortical neurons are often classified by current-frequency relationship. Such a static description is inadequate to interpret neuronal responses to time-varying stimuli. Theoretical studies suggested that single-cell dynamical response properties are neces ...
